GLASS BATTERY BOX.

Application filed January 16, 1926. Serial No. 81,763.

The present invention is directed to an improved multi-cell glass storage battery box-for use in the modern automobile.

What I aim to do, is to provide an exceptionally simple and inexpensive battery box which is characterized in one instance by novel external reinforcing ribs together with supporting ledges or flanges constructed to accommodate conventional retaining means in order that the box may be substituted for the usual types of boxes employed for this purpose.

An equally important feature of construction is in the inclusion of the cells in the box of transversely longitudinally spaced ribs of a height to support the grid plates in spaced relation with respect to the bottom and to provide intervening sediment collectingpockets.

With the foregoing, and other objects in view as the nature of the invention will be better understood the same comprises the novel form, combination, and arrangement -of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawings wherein like reference characters indicate corresponding paits throughout the several. views:

Figure 1' is a view showing the male and female dies of the mold construction in united relation, the female die being shown in'cross section, while the male die is disclosed in side elevation.

Figure 2 is an end elevation of the male die member. I

Figure 3 is a longitudinal section taken substantially upon the line 33 of Figure 1, and looking downwardly in the-direction 0 of the arrows for more clearly disclosing the male die unit assembly.

Figure 4 is a top plan view of the male die, the carrying bar therefor being dis, closed in cross section.

Figure 5 is a top plan view of the female die unit. v

, Figure 6 is a similar View of the battery box molded from glass through medium of the present mold construction. Figure 7 is 5 a view partly in side elevation and partly in cross section of the battery box, and

Figure 8 is a vertical transverse section of the same.

First having reference to Figures 1 to 5 inclusive wherein is disclosed the battery box molding unit comprising generally a female unit 5, and a male unit 6. The female unit 5 of suitable metal is of rectangular box like configuration formed from a pair of half sections a and b of the shape as clearly shown in Figure 5, the sections being interconnected in any desirable manner. Within the center of the bottom wall of the assembled female unit is a relatively square shaped opening 7 into which extends the head 8 of a battery box ejecting die plunger 9 operated by compressed air or any other suitable medium for projection upwardly through the die for obvious partially ejecting the molded battery box from the die member after the molding operation has been completed, and the male member removed.

The interior of the female unit is formed upon its bottom wall with longitudinally and transversely spaced cross channels 10 and 11 respectively, the inner face of the head 8 of the die plunger being formed with complementary channels as clearly'shown in Figures 1 and 5.

Communicating with the cross channels in the bottom wall of this die unit are spaced Vertical channels 12 upon the inner surfaces of the side and end walls of the female die unit, the upper edges of the end walls of which are formed with outwardly extending flanges 1313 the inner edges of which extend above the ends of said walls for providing rabbets 1414:.

The male' die unit 6 constitutes the provision of a rectangular shaped head plate 15, the opposite ends of which are provided with pendent flanges 16-16, Figure 1, between which the cell forming members 17 are adapted to be secured in spaced relation and pendent from said head-plate.

Said cell forming members 17 are maintained in spaced relation from each other and from the flanges16-16 of the head plate 15 through the medium of spacing strips 18,

disposed at the extreme upper ends of the cell forming members. Said spacing members and the cell forming members are formed with registering openings that provide longitudinally extending bores for the reception of relatively elongated headed bolts 19 that are adapted to receive at their unheaded but threaded ends, locking nuts 20.

The flanges 16-16 upon opposite ends of the head plate 15 are suitably slotted for permitting of the proper positioning of the bolts 18 and nuts 20. The strips presented by the slotting of the flanges are secured to the end spacing members by set screws 21 as more clearly disclosed in the longitudinal sectional view, Figure 3.

The head plate 15 is centrally attached to a plunger rod 22 that may be, and preferably is, machine actuated in order that the male die may be positioned within and removed from the female die 5.

The length of the cell forming members 17 are such that the lower ends thereof will be in spaced relation from the bottom wall of'the female unit 5' when the male unit is disposed entirely within said female unit for providing the bottom wall of the battery box which according to the present invention is molded of glass. Furthermore, the sides of these cell forming members 17 are beveled, as clearly disclosed in Figure 1, for providing tapered end walls in the resultant box as well as tapered partition walls for the purpose of adding strength to said walls and for the added urpose of permitting the ready withdrawal of the male unit from the female unit after the box forming material has properly hardened.

The lower edges of the cell forming members 17 are formed .with spaced transversely extending channels 23, while each cell forming member is provided throughout the major portionof its length with two or more circular air chambers 24 that open at the upper ends of the members and into which a c arge of air is to be projected for cooling the same and expediting the hardening of the box forming material.

Projecting through the head plate 15 of the male die unit are pipe sections 25, the lower ends of which alinement with the air cell forming members 17 of said male die unit, while the upper ends thereof are in intercommunication through reason of a pipe line 26 that has communication in an obvious manner with a source of air supply.

It will thus be seen that through the employment of a mold construction as previously described, a one piece glass battery box 27, Figures 6, 7 and 8, will be constructed, and will include a plurality of oblong cells 28, the partition walls 28 of which will be tapered as will also the end walls 30 of said box.

Furthermore the entire exterior surface .Of the box will be provided with reinforcing ribs 31 together with ribs 32 at the bottom of each cell 28. bet 14l4 in the female die unit 5 carrying flanges 33-33 will be present at opposite ends chambers 24 of the terminate in spaced Through reason of the rabof the box at the upper edge thereof, all of which features serve to provide a highly efiicient and strong battery box adapted to be employed as a jar or container for battery elements necessary in the assembly of storage batteries for use in automobiles and the like.

The gist of the present invention is in the making of a storage battery box from glass, this box having a unique physical feature which imparts individuality and makes it highly eflicient in use. As before indicated, one advantage is derived from the provision of the tapered partition walls 29 together with the grid plate supporting ribs 32 which form pockets between the respective ribs for collection of sediment.

The transverse disposition and longitudinal spacing of the ribs is to be noted. A further feature of construction is derived from the provision of notches in the supporting flanges to accommodate customary retaining rods. Moreover, inward of these notches are small depressions to cooperate with the books on the upper end of the customary retaining rod. This makes the box of such construction as to permit it to be substituted for the usual form of box without requiring alterations in support, etc.

' Consequently, an exceptionally advantageous article of manufacture is thus made.

The claims in this application are restricted to the construction of the glass battery box. The latter is closely associated however, with the special die and mold structure which is shown, described, and claimed in an application identified by Serial No. 142,635, filed October 19, 1926.

It is desired that certain modifications in the mold unit may be allowed in order that slight departures may be had from the particular construction or formation of battery box constructed in accordance with the present invention.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is 1. As a new storage battery box made entirely from glass, said box being of general oblong configuration in top plan, being provided with transverse upwardly tapered partitions dividing it internally into transversely elnongated cells, transversely located longitudinally spaced ribs at the bottom of said cells forming intervening sediment collectin pockets and supporting means for grid plates, outstanding supporting flanges at the tops of the end walls of the box, said flanges being notched and provided with depressions inwardly of said notches, together with ex ternal reinforcing ribs formed on the bottom and side and end walls of said box.

2. As a new product of manufacture, a storage battery box made entirely from glass,

product of manufacture, a

gated cells,

forming intervening sediment collecting pockets and supporting means plates,

top of the end walls of the box,

outstanding supporting flanges and external 10 for grid at the reinforcing ribs formed. on the bottom, side and end walls of said box.
